Hi, Michael.

Is there a .bin you've seen by name on code59? They generally don't set up a tune for you. If you're using $42 / 7747 then the $59 .bins are not going to work as they're for a different ecm.

How were you trying to save the .bins from gearhead? Right click, save as sometimes opens a box that has a filename like "attachment.php" or "download.php." If that's happening just change the file nim to the correct one, like anlw5469.bin, and you're good.
